33 Product Description LQ-2170 Service Manual Extensibility request Device ID ESC/P2 IBM 2391 Plus Interface Selection The printer responds to the extensibility request in the affirmative, when the request is 00 H or 04 H, which means: 00 H Request nibble mode of reverse channel transfer. 04 H Request device ID in nibble mode of reverse channel transfer. Refer to the following descriptions: [00 H][32 H]... MFG: EPSON, CMD: ESCPL2-00, MDL: LQ-2170, CLS: PRINTER [00 H][33 H].... MGF: EPSON, CMD: PRPXL24-01, MDL: LQ-2170, CLS: PRINTER The printer has 2 interfaces: the parallel interface and Type B optional interface. These interfaces are selected manually in default setting mode or selected automatically. Manual selection One of 2 interfaces can be selected in default setting mode. Automatic selection Automatic interface is enabled in default setting mode. In automatic interface mode, the printer is initialized to the idle state, where it scans which interface is to be activated. The interface that receives data first is selected. When the host stops data transfer, and the printer is in standby for a number of seconds specified in default setting mode, the printer returns to the idle state. As long as the host sends data or the printer interface is busy, the selected interface remains active. Interface state and interface selection When the parallel interface is not selected, that interface goes into a busy state. When the Type B serial interface card is installed and it is not selected, the interface sends an XOFF code and sets the DTR signal to MARK. When the optional interface is not selected, the printer sends disable commands to the optional interface. When the printer is initialized or returned to the idle state, the parallel interface goes into the ready state, the serial interface sends an XON code and sets the DTR signal to SPACE, and the printer sends an enable command to the optional interface. Remember that interrupt signals, such as the INIT signal on the parallel interface, are not effective unless that interface is selected Prevention Hosts from Data Transfer Time-out Generally, hosts abandon data transfer to peripherals when the peripheral is in the busy state for dozens of seconds continuously. To prevent hosts from this kind of time-out, the printer receives data very slowly, several bytes per minute, even if the printer is in the busy state. This slowdown is started when the rest of the input buffer becomes several hundreds of bytes. Finally, when the input buffer is full, the printer is in busy continuously Rev.A
